Definitions
- the invention relates to a drain, such as a drain hole or drain channel, comprising:
- a collecting container is understood to mean the part of the drain where the water to be discharged is collected in order to then be further discharged via an outflow.
- the collecting container can for instance take the form of a tray, but can also be understood to mean a more closed space in which water is collected.
- Such a drain is known and is often used for discharge of for instance shower water to an outlet pipe.
- the collecting container is usually connected for this purpose to a siphon which is in turn connected to an outlet pipe.
- the collecting container and siphon are incorporated in the floor and finishing layer, such as a tile layer, so that the upper edge of the collecting container lies flush with the upper surface of the finishing layer.
- the drain according to the invention can be installed in a new floor with finishing layer, wherein the finishing layer seals onto the drain. As long as the finishing layer is watertight and the other seals function, no use will be made of the unidirectional passage. Only when a crack occurs in the finishing layer or other seals are defective can possible leakage water still enter the drain via the unidirectional passage. With a drain according to the invention a completely sealed floor with finishing layer can thus be provided which, only in the case of leakage, will still discharge the leakage water reliably as secondary provision.
- the secondary drainage is thus used only when water has permeated under the finishing layer as a result of a failing seal or cracking in the finishing layer.
- the finishing layer is thus not affected by the regular water in the drain tray, as is the case in prior art drain trays.
- the unidirectional passage is further connected to the connecting part, it is possible to arrange this passage not directly against the drain tray but at more of a distance therefrom. A saving in height can hereby be obtained in that the unidirectional passage is not necessarily arranged in the drain tray.
- the outflow of the collecting container is tubular and the connecting part has an opening into which the tubular outflow protrudes. Owing to this tubular outflow the distance between the connecting part and the collecting container can be varied and the height of the collecting container in the floor can thus be adjusted.
- a flexible collar is arranged in the outflow.
- the free edge of the flexible collar preferably lies here against the tubular outflow.
- the flexible collar enables some variation between the position of the connecting part and the position of the collecting container.
- the flexible collar will hold back water rising between the connecting part and the tubular outlet, while possible leakage water falling onto the flexible collar from above can flow into the connecting part because the water will press the flexible collar downward.
- the flexible collar preferably runs along the whole periphery of the tubular outflow, but can also run only partially along the periphery of the tubular outflow.
- a peripheral part of the flexible collar adjacent to the free edge has a substantial directional component the same as the direction of insertion of the outflow. Because the tubular outflow is inserted into the collar, the free edge of the collar will be automatically co-displaced, wherein this edge lies lower than the other part of the collar. Possible leakage water will automatically run over the collar to the free edge and, due to the weight of the leakage water, a small passage will be created between the free edge of the collar and the outflow which will automatically close again. Due to the shape of the collar, water coming from below will however press the free edge further against the outflow, whereby water is prevented from seeping through from below.
- the connecting part is integrated into a siphon.
- the collecting container is an elongate tray of U-shaped cross-section.
- the invention further comprises a method for arranging a drain according to the invention in a floor, the method comprising the steps of:
- a filler piece is arranged over the connecting part before the adhesive is applied, and the adhesive ridges are then arranged directed toward the filler piece, after which the filler piece is then removed.
- the filler piece and the collecting container are preferably elongate.
- a second sealing layer is arranged in the floor.
- a first sealing layer for instance a bitumen layer
- a sand cement layer is subsequently arranged on this first sealing layer.
- a second sealing layer is arranged hereon, after which the finishing layer, such as a tile floor, is arranged.
- the connecting part of the drain can be provided here with two separate unidirectional passages for each sealing layer.
- the unidirectional passage can further also be provided by arranging this passage at a position in the connecting part, or discharge path, such that return flow of waste water via this passage is precluded.
- the drain according to the invention can optionally also be applied on an industrial scale.
- FIG. 1 shows a cross-sectional view of a drain 1 according to the invention.
- Drain 1 has a collecting container 2 with a tubular outflow 3 on the underside.

- Possible leakage water 7 present between finishing layer 8 and floor 4 can flow over flexible collar 6 to outflow 3. As shown in detail in figure 2 , the weight of leakage water 7 will press aside the flexible collar 6 of outflow 3, whereby a passage is created and water can flow away.

Abstract
- a collecting container for collecting water, wherein the collecting container has an outflow on the underside;
- a connecting part for connecting the outflow to an outlet pipe; wherein
the connecting part is provided with a unidirectional passage for admitting water from outside inward into the connecting part.
Description
- The invention relates to a drain, such as a drain hole or drain channel, comprising:
- a collecting container for collecting water, wherein the collecting container has an outflow on the underside;
- a connecting part for connecting the outflow to an outlet pipe.
- A collecting container is understood to mean the part of the drain where the water to be discharged is collected in order to then be further discharged via an outflow. The collecting container can for instance take the form of a tray, but can also be understood to mean a more closed space in which water is collected.
- Such a drain is known and is often used for discharge of for instance shower water to an outlet pipe. The collecting container is usually connected for this purpose to a siphon which is in turn connected to an outlet pipe. The collecting container and siphon are incorporated in the floor and finishing layer, such as a tile layer, so that the upper edge of the collecting container lies flush with the upper surface of the finishing layer.
- In order to prevent falling water permeating between the finishing layer and the collecting container and possibly causing leakage there, it is usual to arrange a sealing mastic layer between the finishing layer and the collecting container.
- If this mastic layer is not replaced after a number of years, leakage may yet still occur. In addition, there is the risk of cracks forming in the finishing layer along which water may permeate between the finishing layer and the floor.
- It is known to provide holes in the side walls of the collecting container at the position of the transition surface between the finishing layer and floor, for instance at the level of the tile adhesive, so that possible leakage water can flow from under the finishing layer into the collecting container. The drawback thereof is that the water from the collecting container can also pass under the finishing layer via the holes. Since the collecting container is partially or wholly filled with drained water during use, in such a prior art collecting container the finishing layer is thus affected from the moment that the collecting container is mounted. Each time the collecting container is used it will thus be possible for water to pass between the finishing layer and the floor via the holes in the side walls. The drained water moreover usually comprises soap residues which affect an adhesive layer between the finishing layer and the floor, whereby for instance tiles are loosened, even if no cracks have yet occurred in the tile layer.
- Similar problems can also occur in drains for industrial application. Particularly in the pasta-processing industry waste water with pasta residues affects the tile adhesive of a normal tile floor. A drain in which holes for possible leakage water are provided in side walls is likewise undesirable in such a case.
- It is now an object to reduce or even obviate the above stated drawbacks. This object is achieved with a drain according to the invention, which is characterized in that the connecting part is provided with a unidirectional passage for admitting water from outside inward into the connecting part.
- By providing a unidirectional passage only water from outside can flow into the collecting container. Water already present in the collecting container is blocked by the unidirectional passage.
- The drain according to the invention can be installed in a new floor with finishing layer, wherein the finishing layer seals onto the drain. As long as the finishing layer is watertight and the other seals function, no use will be made of the unidirectional passage. Only when a crack occurs in the finishing layer or other seals are defective can possible leakage water still enter the drain via the unidirectional passage. With a drain according to the invention a completely sealed floor with finishing layer can thus be provided which, only in the case of leakage, will still discharge the leakage water reliably as secondary provision.
- In the invention the secondary drainage is thus used only when water has permeated under the finishing layer as a result of a failing seal or cracking in the finishing layer. In normal use the finishing layer is thus not affected by the regular water in the drain tray, as is the case in prior art drain trays.
- Because the unidirectional passage is further connected to the connecting part, it is possible to arrange this passage not directly against the drain tray but at more of a distance therefrom. A saving in height can hereby be obtained in that the unidirectional passage is not necessarily arranged in the drain tray.
- In an embodiment of the drain according to the invention the outflow of the collecting container is tubular and the connecting part has an opening into which the tubular outflow protrudes. Owing to this tubular outflow the distance between the connecting part and the collecting container can be varied and the height of the collecting container in the floor can thus be adjusted.
- In a preferred embodiment of the drain according to the invention a flexible collar is arranged in the outflow. The free edge of the flexible collar preferably lies here against the tubular outflow.
- The flexible collar enables some variation between the position of the connecting part and the position of the collecting container. In addition, the flexible collar will hold back water rising between the connecting part and the tubular outlet, while possible leakage water falling onto the flexible collar from above can flow into the connecting part because the water will press the flexible collar downward.
- The flexible collar preferably runs along the whole periphery of the tubular outflow, but can also run only partially along the periphery of the tubular outflow.
- In a highly preferred embodiment of the drain according to the invention a peripheral part of the flexible collar adjacent to the free edge has a substantial directional component the same as the direction of insertion of the outflow. Because the tubular outflow is inserted into the collar, the free edge of the collar will be automatically co-displaced, wherein this edge lies lower than the other part of the collar. Possible leakage water will automatically run over the collar to the free edge and, due to the weight of the leakage water, a small passage will be created between the free edge of the collar and the outflow which will automatically close again. Due to the shape of the collar, water coming from below will however press the free edge further against the outflow, whereby water is prevented from seeping through from below.
- In an embodiment the connecting part is integrated into a siphon. In another embodiment of the invention the collecting container is an elongate tray of U-shaped cross-section.
- The invention further comprises a method for arranging a drain according to the invention in a floor, the method comprising the steps of:
- incorporating, for instance casting, the connecting part into the floor;
- applying an adhesive using an adhesive comb, wherein the adhesive ridges are directed toward the connecting part;
- arranging the collecting container on the connecting part;
- arranging a finishing layer, such as a tile layer, in the adhesive.
- Directing the adhesive ridges toward the connecting part creates channels between the finishing layer and the floor which can guide possible leakage water to the drain.
- In a preferred embodiment of the method according to the invention a filler piece is arranged over the connecting part before the adhesive is applied, and the adhesive ridges are then arranged directed toward the filler piece, after which the filler piece is then removed.
- In the case of a relatively small drain, such as for instance a square drain, it is sufficient to direct the adhesive ridges toward the connecting part. In the case of an elongate drain channel however, leakage may occur along the whole periphery of the channel. By now arranging a filler piece a discharge channel is formed under the collecting container so that leakage water which reaches the drain via the adhesive ridges enters the discharge channel and is then carried to the connecting part.
- The filler piece and the collecting container are preferably elongate.
- In some cases a second sealing layer is arranged in the floor. An example hereof is that a first sealing layer, for instance a bitumen layer, is arranged on the concrete floor. A sand cement layer is subsequently arranged on this first sealing layer. A second sealing layer is arranged hereon, after which the finishing layer, such as a tile floor, is arranged.
- It is possible to provide the unidirectional passage according to the invention for each of the sealing levels. The connecting part of the drain can be provided here with two separate unidirectional passages for each sealing layer.
- The unidirectional passage can further also be provided by arranging this passage at a position in the connecting part, or discharge path, such that return flow of waste water via this passage is precluded.
- Although the invention is particularly suitable for application in the sanitary field, the drain according to the invention can optionally also be applied on an industrial scale.
- These and other features of the invention are further elucidated with reference to the accompanying drawings.

membrane 71 can further be arranged onupper flange 67 of connectingpart 63. -
Figure 11 shows asixth embodiment 80 of a drain according to the invention. Thisdrain 80 has a collectingcontainer 81. A connectingpart 82 is placed in this collectingcontainer 81. This connectingpart 82 is formed from a thin double-folded plate, which also provides for the finishing of atile layer 83. -
Unidirectional passages 84 are provided in the connecting part close to the bottom of collectingcontainer 81. Possible leakage water permeating undertile layer 83 can flow via these passages into collectingcontainer 81. -
Tile layer 83 is sealed onto connectingpart 82 using a sealingmastic 85. A watertight whole is thus ensured. -
Figures 12 and13 show aseventh embodiment 90 of a drain according to the invention. - In this
embodiment 90 the collecting container and the connecting part take an integral form. The drain is provided with ahorizontal flange 91 with a square,upright flange 92 thereon. Thisupright flange 92 forms a boundary fortile layer 93.Flange 92 is sealed ontotile layer 93 via a sealingmastic 103. - A siphon
housing 94 with anoutlet pipe 95 is arranged underhorizontal flange 91. Aremovable inflow part 96 is arranged centrally in siphonhousing 94. Thisinflow part 96 seals onto siphonhousing 94 via an O-ring 97. - O-
ring 97 is provided with a dependingedge 98 which thereby seals apassage opening 99. Possible leakage water can flow via this passage opening 99 into siphonhousing 94. The leakage water flows from undertile layer 93 viapassage 100 andchannel 101 topassage opening 99. - A closable inspection opening 102 can further also be provided in
horizontal flange 91 for visual monitoring of possible leakage. Via this inspection opening 102 it is possible to periodically monitor whether any leakage has occurred. Depending on the result of this monitoring, the leakage can then be repaired.
